I can start working on this right away if you can "reserve" the bounty for me. Thank you.
Hi, I'm glad you are interested! 0.5 BTC bounty will be 'reserved' for you for one week (in other words, bounty will be offered to someone else if you won't be able to deliver working solution till 12.12.2013). Is that OK with you?
Send me PM if you want some kind of escrow or if there are any other questions.
